please answer question 1-4 with a breif explanation
thankyou
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. In a certain species...

In dogs, short hair is dominant over long hair, and dark coat
color is dominant over albino fur. Assuming that these effects are
caused by two independently sorting genes, what will be the result
of the following cross? Create a Punnet square and show your
work.

A particular plant has a gene for flower color and a gene for height with the following phenotypes: RR: red flower TT: tail Rr, rr: white flower Tt: medium tt: dwarf If two plants (RrTt times RrTt) are crossed, how many phenotypes can be produced in F1? 1 2 4 6 9 Eye color is an autosomal (non-sex) trait.

Fill in the blanks
1.
There is a gene for height in a species of pea plant that we will
call "T gene". We would denote the dominant allele for this gene as
_____ and the recessive allele as _____. A homozygous dominant
individual's genotype would be _____, a homozygous recessive
individual's genotype would be _____, and a heterozygous
individual's genotype would be _____.
2. If this gene for height in pea plants shows complete
dominance (where the dominant allele...

1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...

17. A diploid plant is a dihybrid for flower color (gene “R”)
and leaf size (gene “L”). Its
phenotype is red flowers and large leaves. This plant is crossed to
a tester plant (which has
white flowers and small leaves). The progeny is as follows:
23 Red, large
25 White, small
230 Red, small
235 White, large
What can be concluded about the linkage relationship of the loci in
the dihybrid parent?
A) Genes R and L are unlinked
B)...

Flower color is incompletely dominant in snapdragons. If a white-flowered plant (WW) is crossed with a red-flowered plant (RR), all of the offspring are pink (RW). What is the probability of getting pink-flowered offspring from two pink-flowered parents? Show your work. 1 point Probability of getting pink-flowered offspring: __________________ % Reminders about human blood type genetics. • ABO blood types o A and B alleles are co-dominant o A allele is dominant to O allele o B allele is dominant...
