Homework Answers
mushroom colour is dtermined by one gene, there three different phenotypes, red, white, piebald, piebald is a mixture both red and white paches so the piebald shows co-dominance,
A-red
a-white
Aa-piebald, AA-red, aa-white
a) piebald* piebald
Aa * Aa
| A | a | |
| A | AA (red) | Aa (piebald) |
| a | Aa ( piebald) | aa (white) |

1. The presence of short hairs on the leaves of tomato plants is a dominant trait controlled by the allele H.The corresponding recessive trait, smooth leaf, is found in plants with the genotype hh. The table below shows the progeny of three independent crosses of parental plants with genotypes and phenotypes that are unknown. Number of Progeny Hairy Leaf Smooth Leaf Cross 1: Cross 2: Cross 3: 32 42 45 24 Examine the distributions of phenotypes in the progeny of...

Question 1 (1 point) In a species of flowering plant, petal color is determined by one gene with two alleles, R and W. Individuals homozygous for allele R have red petals, and those homozygous for allele Whave white petals. Ris dominant to W. You cross a pure- breeding red flowered plant with a pure-breeding white flowered plant to create an F1 generation. You then cross two individuals from the F1 generation to create an F2 generation. What proportion of the...

1. In humans, red-green color-blindness is a sex-linked (carried on the X chromosome) recessive trait. If a woman who is not color blind but whose father was color-blind marries a man who is not color-blind, what is the probability that their first child will be a daughter who is color- blind? a) 0 b) 25% c) 50%- d) 100%- e) cannot tell from the information given 2.

Question 10 (1 point) In Drosophila, the mutant black (b) has a black body and the wild-type (b+) has a gray body; the mutant vestigial (v) has wings that are short and crumpled compared the long wild-type wings (V+). These genes are linked and are located on the X- chromosome. A cross between a female fly and a black, vestigial winged male fly produced the following progeny: gray (b+), normal (v+) 20 gray (b+), vestigial (v)...

Use the information below to answer questions 1-2. Leather back turtles (Dermochelys coriacea) lay 50 eggs per clutch on soft sand beaches. Let us assume that the first and second cleavage within the developing eggs is controlled by the presence of a single pair of codominant alleles, CA and C Full cleavage and development to maturity will occur if an offspring bears alleles in the heterozygous (CAC) condition. However, there is only 18% cleavage penetrance if C Cappears in the...
