Genetics

This is not very likely.

DNA doubles and produces sister chromatids before meiosis begins.

the chromosomes must replicate

Yy

a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.

Color blindness is a recessive sex linked trait.

Cause attached earlobes are the dominant trait. Unattached earlobes are reccessive.

F2 Generation

M Phase

Wrinkled seeds are recessive

The F1generation carried recessive alleles.

If seed shape did not have a clearly recessive form

DNA is replicated during the S phase of the cell cycle. If DNA is not replicated then the new cell will not have a copy of the DNA. If it does not have a copy of the DNA, then the cell will not be able to function properly.

if seed color and shape were located on the same chromosome
