The answer is C. Hope this helps :)
Answer:
In this cross aabb is the only genotype that is homozygous for both traits among 16 offspring's produced during the AaBb × AaBb cross.
Proportion is: 16 : 1 i.e out of 16 only one is homozygous for both traits.
Explanation:
Taking an example of pea plant.
In this question each organism has hetero-zygous alleles i.e Aa of single character gene with having both dominant and recessive traits.
Say for example in this case capital "A" represents Tall dominant character and small "a" represents dwarf recessive character. Similarly Capital "B" for example represents round dominant pea seeds and small "b" represents wrinkled recessive pea seeds.
In this question organism with having hetero-zygous characters (i.e having both dominant and recessive traits) are crossed. Underlined represents male part while non-underlined represents Female part of plant
AaBb × AaBb-----------(1)
Four different types of gametes are produced from each organism due to meiosis in which chromosomes become half and alleles become separated.
i.e AB, Ab, aB and ab× AB, Ab, aB and ab--------------(2)
Mating of these alleles are represented below in the form of checker board.
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
In this cross aabb is the only genotype that is homozygous for both traits among 16 offspring's produced during the AaBb × AaBb cross.
Proportion is: 16 : 1
1 2.45 g
2 2.40 g
3 2.42 g
which of the following best describes the students measurements
the students measurements were accurate, but not precise
the students measurements were precise, but not accurate
the measurements are neither accurate nor precise
the measurements are both accurate and precise
Answer:
Option , B, the students measurements were precise, but not accurate
Explanation:
It is given that the acceptable value for the paper clips is 1.14 grams.
An accurate value is the one which is close enough to the accurate answer and in case when the number of readings taken with in an experiment are close to each other then they are said to be precise.
Here the value obtained through three reading are close to each other hence, they are precise but none of these values is close to the acceptable value for the paper clips.
Hence, option B is correct.
Answer:
The correct answer is karyotype.
Explanation:
A karyotype is an image that helps in analysis to a person's chromosome. It is a picture of all chromosomes of an individual. Scientists take this picture or image sample of chromosomes of the individual is isolated, stained or examined under the microscope. This image helps in analysis and study of the chromosome.
Thus, the correct answer is karyotype.
She is using a karyotype
