Lincoln Red cattle are entirely red. Hereford cattle have a white face. The white face is due to a dominant allele for which Hereford breed is homozygous. A farmer has a herd of Lincoln Red cows and Larry, a Lincoln Red bull. Larry was allowed to mate with cows but died of exhaustion before he had fertilized the whole herd. The farmer borrowed a neighbour’s Hereford bull called Herbert to finish Larry’s job. When the calves were born, the farmer found he could distinguish between Larry’s and Herbert’s offspring. How? He kept one of Herbert’s male offspring to replace Larry. When this bull was mated to the Lincoln Red cows, what would be the phenotypes of the calves and in what proportions?

Spoink is a Pokemon character with a spring tail. It must bounce continuously or it will die. Imagine that the spring in the tail is controlled by a single gene with two alleles T and t. Individuals with the genotype TT have very stiff tails that take a lot of energy to bounce, Tt have just the right amount of spring, and those with tt tails have very floppy tails that deform after long periods of bouncing, making it very difficult to continue bouncing. The genotype frequency in this population is: TT=25% Tt=70% tt=5% Part A:  The frequency of the t allele in the population is  ___%. The expected frequency of the Tt genotype in the population is ___%. Part B: Is the population of Spoink in Hardy-Weinberg Equilibrium? A. Yes B. No Rationale? Part C: What type of selection, if at all, might be operating on Spoink tails springy-ness?  A. Stabilizing Selection B. Balancing Selection C. Directional Selection D. Disruptive Selection E. No selection is occurring; population is in…

Body color in Drosophila is X-linked. Imagine a gene where allele E is dominant and produces gray bodies, while allele e is recessive and produces yellow bodies. If a homozygous yellow female is crossed with a grey male, the progeny would be 3 gray females : 1 yellow male O 1 gray female : 1 yellow female : 1 gray male : 1 yellow male O all females are gray and all males are yellow. 9 gray females : 3 yellow females : 3 gray males : 1 yellow male

Brown eyes are dominant over blue eyes. This is NOT a sex linked trait. Cross a brown eyed Color blind male (whose mother had blue eyes) with a normal blue eyed female (whose father was colorblind)

Can you please not type the answer can you write it on a paper

It would be nice if you can give me some explanation please Number 6

A backyard homesteader that wants to expand the amount of cute duck breeds. They know the f gene codes for feather coloring (black feathers (F) are dominant to white feathers (f)) while the b gene codes for feet color (grey feet (B) are dominant to orange feet (b)). The homesteader crosses a super fertile heterozygous wild-type duck that has black feathers with grey feet (FfBb) with a homozygous recessive duck with white feathers and orange feet (ffbb). This produces 100 offspring.  2. Which are parental phenotypes? (2 answers)
