Explanation:
Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.

Image result for why was domesticating and confining animals so important to the food supply of early civilization
Throughout history, people have bred domesticated animals to promote certain traits. Domestic animals are chosen for their ability to breed in captivity and for their calm temperament. Their ability to resist disease and survive in difficult climates is also valuable.

Answer:
The correct answer is -
P1: SSyy
p2: ssYY
Explanation:
In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.
It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.
