Among humans, tallness is dominant over shortness. If a heterozygous tall male marries a homozygous short female, what would be the appearance of the children?

Among cats, short hair is dominant over long hair. If a homozygous short hair male were mated with a homozygous long hair female, what type of hair would the kittens have?

Answer #1

1) Heterozygous tall (dominant) X Homozygous short (recessive)

Tt X tt

Offsprings Tt, Tt, tt,tt

T t
t Tt tt
t Tt tt

Appearance of Children = 50% tall and 50% short

2) Homozygous short hair (Dominant) X homozygous long hair (recessive)

SS X ss

S S
s Ss Ss
s Ss Ss

All kittens have Ss that is short hair (heterozygous dominant)

3) heterozygous yellow (dominant) X heterozygous yellow (dominant)

Yy X Yy

Y y
Y YY Yy
y Yy yy

Seeds of F1 generation - 3:1 - 3 yellow seed (YY,Yy,Yy) : 1 green (yy)

3a. In a certain breed of dog long hair is dominant over short hair; the gene involved is autosomal. Another gene, B controls hair colour, which is X-linked, one allele B1 produces gray coloured hair; the other allele B2 produces red coloured hair; and the heterozygous combination B1B2 produces brindle coloured hair (a mix with patches of both gray and red coloured hairs). If a red male homozygous for long hair is mated with a brindle short-haired female, what kind...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
