Question

If hornless (H) in cattle is dominant over horned (h) and two homozygous cattle,

one hornless and the other horned are crossed, what will be the genotype and the
phenotype of the first generation?

Answer 1

Step-by-step explanation:

We are given that H gene responsible for hornless in cattle is dominant over h gene for horned cattle .

The parents taken for cross are homozygous for their character, one horned and other hornless are crossed . The genotype would be HH and hh respectively.

For cross refer to the attachment.

From the cross we can see that,

• The genotypic of all the offsprings for the
  `F_1` generation is Hh .
• Since H is dominant over h therefore the phenotype would be hornlessnes for all the offsprings.
