A male Tiggydon is homozygous recessive for both wacky wings (w) and flashy feathers (f). He is crossed with a female who is homozygous dominant (normal wings and normal feathers) for both traits. What are the genotypes of those exotic birds? (female - male)
A) wwff - WwFf
B) wwFF - WWFF
C) WWFF - wwff
D) WwFf - wwff

As we know that the genotype is the feature of the genetic design of a cell, which defines one of its attributes. If a male Tiggydon is homozygous recessive for both wacky wings (w) and flashy feathers (f). He is crossed with a female who is homozygous dominant (normal wings and normal feathers) for both traits. Then the genotypes of those exotic birds will be (female: WWFF - male: wwff). As mentioned in the question that the dominance of the female is more, so the answer will option C.

Answer:

C) WWFF - wwff

Explanation:

First of all it is important that you know that dominant alleles are represented by capital letters, while recessive alleles are represented by lowercase letters. In addition, you also need to know which homozygous organisms are those that have two equal alleles. When these two alleles are recessive, we call these organisms homozygous recessive; when these alleles are dominant, we call these organisms dominant homozygotes. When one organism has a recessive allele and the other is dominant, it is called heterozygous and only expresses the dominant characteristic. With this we can say that the recessive characteristics are only expressed when the organism is homozygous recessive.

Based on this, we can say that the genotype for a homozygous recessive bird for both crazy (w) and flashy feathers (f) is "wwff", while the genotype for a homozygous dominant bird (normal wings and normal feathers) for both characteristics, it is "WWFF".
