The Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square represents a cross between a mom who is heterozygous for dimples and a dad who is homozygous for no dimples?A Punnett square is shown. The columns are labeled Upper D and Upper D. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, Upper D d, Upper D d, Upper D d.

Answer:

A Punnett square is shown. The columns are labeled Upper D and d. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, d d, d d, Upper D d.

Explanation:

Punnett square is used to depict the cross between two organisms. Progeny genotypes can be determined by punnett square. Columns and rows are labelled according to the alleles present in the genotype of respective parents, in this case the mom and the dad.

It has been given that the mom is heterozygous for dimples trait. Since, heterozygous genotype has two different alleles together, mom's genotype must be Dd. Dad is homozygous for no dimples so he can either be DD or dd depending on the dominance nature of the trait. Out of the given options, only the selected option has one heterozygous genotype (Dd) and one homozygous genotype (dd) together hence it is the correct option.

An object at rest will stay at rest and an object in motion will stay in motion at a constant speed and in the same direction, unless acted on by an unbalanced force.” The statement above is Newton’s first hypothesis of motion because it makes a prediction. theory of motion because it is a widely accepted explanation. law of motion because it is a factual statement based on observations. explanation of motion because it is widely accepted and based on observations.

Answers

The statement that 'an object at rest will continue to stay at rest and an object in motion will stay in motion in same direction and at constant speed unless some external force acts on the object' is a law of motion. This statement describes a fact which is base don the observations made by Newton. It is universally true and hence, it is not a hypothesis, or theory but a law.

Hence, the correct answer is 'law of motion because it is factual and based on observations'.
This would be Newton's first law of motion as it is a factual statement based on observations.

Which of the following occurs in meiosis but not in mitosis? A) chromosome replication
B) synapsis of chromosomes
C) production of daughter cells
D) alignment of chromosomes at the equator
E) condensation of chromatin

Answers

The process that occurs in meiosis but not in mitosis is: synapsis of chromosomes

MEIOSIS AND MITOSIS:

  • Meiosis is a kind of cell division that results in the production of four daughter cells (haploid) that are genetically different from one another.

  • Meiosis occurs in different stages namely: prophase, metaphase, anaphase and telophase.

  • In the prophase stage, homologous chromosomes lie side by side to form a structure called tetrad. This process is called synapsis.

  • Synapsis of chromosomes is unique to only meiotic division and hence, does not occur in mitotic division.

Final answer:

The process that is unique to meiosis and not found in mitosis is synapsis of chromosomes, which happens during prophase I of meiosis. This involves the pairing of homologous chromosomes and the formation of tetrads leading to genetic variation.

Explanation:

Among the options provided, the process that occurs in meiosis but not in mitosis is the synapsis of chromosomes (option B). Synapsis happens during the prophase I of meiosis, where homologous chromosomes pair up aligning their genes in a process known as synapsis. This is unique to meiosis and results in the formation of tetrads which eventually leads to genetic variation due to crossing over. In contrast in mitosis which is involved in somatic cell division, homologous chromosomes do not pair up or form tetrads.

Which term describes the chromosomal abnormality of having three copies of a single chromosome? haploidy diploidy triploidy tetraploidy

Answers

Trisomy is the answer.A trisomy is a chromosome abnormality in which a person has three copies of a particular chromosome rather than the expected two.Trisomies can have varying effects on a person's health depending on which chromosome is affected by the trisomy. Some trisomies such as trisomy x have only mild effects whereas others such as trisomy 21 also known as Down syndrome result in health problems and development delays.Many Trisomies can have fatal consequences such as trisomy 16 or trisomy 18 .They frequently cause miscarriages or loss of the baby shortly after birth.

Answer:

the answer is trisomy
