~ 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?

Homework Answers

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.

You are examining two traits of a plant called Trait A and Trait B. Each trait is associated with a different gene on a different chromosome. Trait A shows: the same phenotype for both the heterozygous and homozygous dominant allele combinations a different phenotype for the homozygous recessive allele combination. Trait B shows: three different phenotypes, each associated with only one of the three possible allele combinations. A) Describe the type of inheritance associated with Trait A and describe the...

"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
