A female Arctic Hare, who’s recessive for a spade-shaped tail, but heterozygous for a fluffy tail, mates with a male Arctic Hare, who’s heterozygous for a round cotton-tail, but homozygous dominant for a fluffy tail.Out of 16, how many baby bunnies will have a spade shaped, fluffy tail?

1/2

A female Arctic Hare, who’s recessive for a spade-shaped tail, but heterozygous for a fluffy tail, mates with a male Arctic Hare, who’s heterozygous for a round cotton-tail, but homozygous dominant for a fluffy tail. What is the female’s genotype?

In Arctic Hares, a cream nose with long whiskers is dominant over a brown nose with short whiskers. A female Arctic Hare, who’s homozygous for a brown nose and short whiskers mates with a male bunny rabbit who’s heterozygous for both a cream nose and long whiskers. What is the female’s genotype?

In Arctic Hares, a cream nose with long whiskers is dominant over a brown nose with short whiskers. A female Arctic Hare, who’s homozygous for a brown nose and short whiskers mates with a male bunny rabbit who’s heterozygous for both a cream nose and long whiskers. What is the male’s genotype?

NnWw

Both alleles are equally dominant

Since one allele is not completely dominant over another we can no longer use just one uppercase or lowercase letter like with normal punnett squares. Instead, we have to use two different letters that are both

Capitals to show equal dom

Incomplete Dominance

One allele is not completely dom

The heterozygous phenotype is a blended mix between the two

Homozygous phenotypes

Multiple Alleles

Genes with 2+ alleles

The codominant blood type is

AB

Polygenic Traits

Traits controlled by 2+ genes

Every other chromosome

X-Linked Traits

X sex chromo trait

Heterozygous carrying a recessive trait unaffected

Carrier

XbY

The father is colorblind, which is a recessive X-linked trait. The couple’s first child is a boy who is also colorblind.What is their first child’s genotype? (b came from mom since its an Xb)
