Question

~ Part I: Rules ~ Dominance and Recessive Traits

(1.) What is the chromosome number (“n”) for the dragons?

(2.) Which trait(s) exhibit incomplete dominance?

(3.) What does it mean for a trait to be incompletely dominant?

(4.) No allelic combination is described as being heterozygous recessive. Why do you think this is the case? Some Traits are Sex-linked

(5.) Which dragon trait(s) is/are sex-linked?

(6.) How do sex-linked traits differ from autosomal traits? Color and Lethal Combinations

(7.) Describe how the inheritance of color is different from that of horns and/or wings.

(8.) On which chromosome is the lethal combination exhibited? What is the lethal combination?

Answer 1

Since you hav eposted multiple questions, I am going to answer first four. I hope it helps. Thanks

1. The chromosome number for the dragons is 6.

2. The trait for legs exhibits incomplete dominance

3. A trait is considered to be incompletely dominant when it has an intermediate phenotype between two parents.

4.There is no allelic combination described as being heterozygous recessive because one allele would be the recessive allele and the other would be the dominant allele. The dominant allele would show through rather than the recessive allele, so it would not be called heterozygous recessive because the recessive trait would not be seen.
