Answer #1

Answer:

The trait is best descrive as a sex limited trait.

H=horn ; h = hornless

XX;Hh (female) x (male) XY; hh ----Parents

Xh

Yh

XH

XX; Hh (hornless female)

XY; Hh (horned male)

Xh

XX; hh (hornless female)

XY; hh (hornless male)

Horned females =0%

Hornless females = 50%

Horned males = 25%

Hornless males = 25%

    Genetics Question The presence of a beard on some goats is determined by an autosomal gene that is dominant in males and recessive in females. Heterozygous males are bearded, while heterozygous females are beardless. What type of inheritance is exhibited by this trait? Sex-influenced Autosomal dominant Autosomal recessive Sex-linked Sex-limited

    6. In goats, beards are produced by an autosomal allele that is expressed differently in males and females: The bearded allele (Bº) is dominant over the beardless allele (B") in males, but recessive in females. Therefore, males only need one copy of the bearded allele to be bearded, but females need two copies of the bearded allele to be bearded. Another independently assorting autosomal allele determines coat color: black coat (L) is completely dominant over white coat (1). For each...

    3) The presence of spots in a ladybug species is controlled by a single locus. The allele S produces spots while the allele s produces no spots. A breeding study shows that S is completely dominant to s. In a random sample of 758 individuals, 28 completely lack spots. a) What are the expected frequencies of the three genotypes in this population and what assumption(s) did you make to solve this problem? b) What are the allele frequencies? 4) In...

    Assume red plumage is encoded by an autosomal dominant allele (R). You crossed a male robin with a red breast and a homozygous dominant genotype with a female robin with a homozygous recessive genotype. You get both male and female offspring, but find that only the male offspring have a red breast. How could you explain this? Group of answer choices a The red plumage has variable expressivity in males b The plumage gene is not present in females c...

    Given: There is a two locus two allele system for a particular species of African antelope. One locus controls horn length and the two alleles are H and h. (HH) gives long horns, (Hh) gives short horns, and (hh) gives no horns. Only males can have horns. The second locus controls color pattern and has two alleles D and d. (DD) gives a dark color pattern to the face, (Dd) gives a dark color pattern to the face, and (dd)...
