Question

Cross a heterozygous green skinned zork with a yellow skinned zork.

Answer 1

Answer: When heterozygous green skinned zork is crossed with a yellow skinned zork, they will produce two types of offspring that are- green skinned and yellow skinned zork.  

Explanation-

As per the information in the question, green skinned zork has heterozygous genotype ( let us consider 'Gg'), which indicates that green skin is a dominant trait. This is because dominant allele ( a variant of gene that is depicted by capital letter) always expresses itself over the recessive allele.

Recessive allele is expressed only when present in a homozygous condition ( such as yellow skin in this question is a recessive trait with genotype 'gg').

The genotypes of parent are- Gg (heterozygous green skinned zork) and gg (yellow skinned zork).

When they are crossed, they will produce two types of offspring that are- green skinned and yellow skinned zork.
