What are the expected genotypes of a cross between two homozygous dominant parents?

All homozygous dominant offspring

What phenotypic ratio would the offspring of two heterozygous parents for blonde hair have? Brown hair is the recessive trait.

Blonde : Brown 3:1

What would be the genotypic ratio of offspring be if one person with blue eyes, and one person with green eyes (heterozygous) mated. Blue eyes are recessive to green eyes.

Gg : gg 2:2 1:1

If rolling tongue is a dominant trait, what would the parent genotypes be if offspring appeared to have the following genotypes: RR, Rr, rr

Rr x Rr

Describe Mendel’s Experiment with pea plants allowing the monohybrid cross to be created.

Mendel started with pure purple and white flowers. He crossed these, and all flowers were purple. He then took two of the offspring and crossed them. The result from this cross was that most of the flowers were purple, however a few were white.

In a Pedigree, what does a square represent?

A male

What is an example of a way a pedigree can be used?

Show how a trait is passed from one generation to the other, Determine whether allele is dominant or recessive, Determine whether a trait is inherited.

The symbol shown in this is picture is the symbol for _______.

Seperation

Would individual II-2 be homozygous or heterozygous for albinism

Heterozygous

Which genotype is not correct in the following pedigree? ff Ff FF ff Ff ff Ff

What are the first three steps when doing a dihybrid cross?

Allele definitions Cross of parents Gamete Combinations

What are the first three steps when doing a monohybrid cross?

1.Allele definitions 2.Cross of parents 3.Punnett Square

What are the possible gamete combinations for the following cross: (Mom) x (Dad) RrGG x RRGg

Mom:RG, rG Dad: RG, Rg

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d).. If a squash plant true-breeding for white, disk-shaped fruit is crossed with a plant true-breeding for yellow, sphere-shaped fruit, what will the genotypic ratios be for the F1 generation?

WwDd 1:0 100%

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d).. If a squash plant true-breeding for white, disk-shaped fruit is crossed with a plant true-breeding for yellow, sphere-shaped fruit, what will the phenotypic ratios be for the F2 generation?

White, disk-shaped: 9 White, sphere-shaped: 3 Yellow, disk-shaped: 3 Yellow, sphere-shaped: 1

Who developed the model of DNA?

Watson and Crick

What is the law of independent assortment?

Genes for different traits are sorted independently of one another.

Why do we show two alleles in a genotype instead of just one?

One allele is on each of the chromosomes in a pair.

The genes an organism has for a particular trait.

genotype

Who is the “father of genetics” and why is he called this?

Gregor Mendel and he figured out patterns of traits in offspring
