Every living organism has a scientific name that is classified into several hierarchical groups, including domain, kingdom, phylum, class, order, family, genus, and species. This classification system helps scientists organize and understand the diversity of life on Earth.
1. Domain: This group represents the highest level of classification and categorizes organisms into three domains: Archaea, Bacteria, and Eukarya. Archaea and Bacteria contain prokaryotic organisms, while Eukarya includes eukaryotic organisms.
2. Kingdom: Within each domain, organisms are further classified into different kingdoms. For example, in the domain Eukarya, there are kingdoms such as Animalia, Plantae, Fungi, Protista, and more. Each kingdom includes organisms with similar characteristics and evolutionary relationships.
3. Phylum: The phylum is the next level of classification and groups organisms based on certain shared characteristics. For example, in the animal kingdom, phyla include Chordata (which includes vertebrates) and Arthropoda (which includes insects, spiders, and crustaceans).
4. Class: Within each phylum, organisms are further divided into classes based on additional shared characteristics. For example, in the class Mammalia, animals have mammary glands and give birth to live young.
5. Order: Orders are the next level of classification and further divide organisms within a class based on shared characteristics. For example, within the order Carnivora, animals have specialized teeth for eating meat.
6. Family: Families group organisms within an order based on more specific shared characteristics. For example, within the family Felidae, animals have retractable claws and are known as cats.
7. Genus: The genus is a more specific classification group that groups closely related species together. For example, the genus Panthera includes big cats such as lions, tigers, and leopards.
8. Species: The species is the most specific level of classification and refers to a group of organisms that can interbreed and produce fertile offspring. Each species has a unique scientific name, consisting of the genus and species names. For example, the scientific name for lions is Panthera leo.

1. Explain the inheritance pattern of the ear lobe attachment trait. Explain bow you determined this.
2. Explain the two inheritance patterns of blood type.
3. What did you determine Joseph's blood type to be? include genotype and phenotype. Explain how you
determined this, including Pumnett Squares to support your reasoning
In complete dominance, the dominant allele hides the expression of the recessive allele. In codominance, both alleles are expressed. 1. Complete dominance / 2. Complete dominance and codominance / 3. Genotype: IBi +- and Phenotype B Rh+.
------------------------------------------------
1. Explain the inheritance pattern of the ear lobe attachment trait. Explain bow you determined this.
Earlobe attachment is controlled by a single, autosomal, diallelic gene. Let us say that
The inheritance pattern of the earlobe attachment is simple Mendelian inheritance showing complete dominance.
According to allelic combination, each individual will express a phenotype that is the product of a mixture between both parents' genetic charges.
Following the first Mendel principle, each individual has a pair of alleles, and each allele codes for an alternative form of the same trait -for instance, attached and free-. These alleles independently segregate during gamete formation.
In complete dominance, the dominant allele completely masks the recessive allele expression. This is evident in heter0zyg0us individuals that carry both alleles but only express the dominant phenotype.
2. Explain the two inheritance patterns of blood type.
The gene that determines the ABOblood type of a person is a triallelic gene.
According to the allelic combination, the inheritance pattern might be either complete dominance or codominance.
Alleles are IA, IB, and i.
→ H0m0zyg0us dominant or heter0zyg0us Individuals IAIA or IAi will express the A blood type.
→ H0m0zyg0us dominant or heter0zyg0us Individuals IBIB or IBi will express the B blood type
→ Individuals with h0m0zyg0us recessive genotype, ii will express the 0 blood type.
→ Individuals carrying IA and IB alleles will express the ABblood type.
The Rh factor expresses complete dominance, where the + allele is dominant over the - allele. So whenever the + allele is present, either in h0m0zyg0us or heter0zyg0us state, the individual will express Rh+ factor.
3. What did you determine Joseph's blood type to be?
We know that
Rh factor
Cross: Joseph x Rita
Phenotypes) Rh+ x Rh-
Parentals) + - x --
Gametes) + - - -
Punnett square) + -
- +- --
- +- --
F1) 50% of the progeny is Rh + ⇒ heter0zyg0us genotype +-
50% of the progeny is Rh - ⇒ h0m0zyg0us genotype --
ABO
Cross: Joseph x Rita
Phenotypes) B x AB
Parentals) IBi x IAIB
Gametes) IB i IA IB
Punnett square) IB i
IA IAIB IAi
IB IBIB IBi
F1) 25% of the progeny is AB ⇒ Genotype IAIB
50% of the progeny is B ⇒ 25% IBIB + 25% IBi
25% of the progeny is A ⇒ Genotype IAi ⇒ The daughter
So, Joseph's blood type is B and Rh+

Answer:
1. The shape of the earlobe is determined by a single autosomal gene, with two alleles: the dominant allele (F) expresses a detached (or free-hangning) earlobe, whereas the recessive allele (f) determines an attached earlobe. The potential dominant/recessive combinantions can yield different patterns of inheritance depending on what the allele combination is present in the progenitors (e.g. if both parents are FF, 100% of the progeny will be FF and presenting free earlobes; if one parent is Ff and the other is ff, then the inheritance pattern will be 50% free earlobes 50% attached earlobes.
2. Like the earlobe trait, the inheritance pattern of blood type depends on the combination of alleles, in this case THREE: A, B, and O. A and B are dominant, O is recessive. The Rh factor is determined by the presence (Rh+) or absence (Rh-) of a particular gene (RHD), and is independent from blood type.
3. Joseph's blood Rh factor is +, and his blood type is
Explanation:
1. This is a case of simple Mendelian inheritance. During meiosis, each chromosome will take with it one copy of the allele (e.g., in an individual with Ff genes, one gamete will end up carrying F, the other will end up carrying f). Since this sorting out of alleles is random, there is a random chance that either an F carrying gamete or an f carrying gamete to fuse with a gamete of the opposite gender (carrying in time F or f) to produce the zygote. A Punnett square can be used to show the resulting probabilities (see Question 3).
2. In this case we have two different types of patterns. One given by three allele versions of the same gene, A, B (the dominants), and O, resulting in types A (alleles AA or AO), B (BB or BO), AB (both AB alleles present) and O (OO). The blood type depends on a series of antigens expressed in the cellular membrane, with O alleles expressing none. In the case of the Rh factor, it is inherited independently from blood type as it is coded in a different gene.
3. Joseph's blood factor is Rh+ as some of his progeny with an Rh- partner is Rh +. His blood type is BO, since, even though none of Joseph and Rita's sons or daughters is blood type O, one of their daughters (A type) married a B type and had an O type son. This means that both parents had to have an recessive O allele masked by the dominant allele. Claire has to have inherited this O allele from Joseph as Rita is blood type AB. Punnett square below illustrates this
Joseph
B O
Rita A AB AO
B BB BO
this explains all four blood types from their progeny, with genotypes AO and BO yielding A and B blood types respectively.
