The process of meiosis creates new combinations of genetic material in each of the four gamete cells. These new combinations result from the exchange of DNA between paired chromosomes in a process called crossing-over. This process creates ______ in each gamete.

During Prophase I of Meiosis, which process occurs when homologous chromosomes exchange segments of DNA to add variation to the offspring as seen in the image attached?

The law of independent assortment states that the inheritance of alleles for one trait is not affected by the inheritance of alleles for a different trait if the genes for the traits are on __________________.

In cats, coat color for orange tabby is considered dominant over white coat color. What is the probability of orange tabby offspring from parents that are heterozygous for this coat trait?

Black fur is considered dominant over yellow fur in Labrador Retrievers.

What is the probability of black fur in offspring of parents that are heterzygous for the trait?

In humans, curly hair is considered dominant over straight hair. If a heterozygous female mates with a male that is homozygous for straight hair, what is the probability that the offspring will be born with curly hair?

For a person to be left-handed, that is considered to be recessive to the more dominant trait for right-handedness.

What is the probability of an offspring being right-handed with the cross of a male that is homozygous for right handed to a female that is homozygous for left-handed?

In parrots, green feathers is dominant over blue feathers. If a parrot breeder wants to breed only blue parrots, what parental genotypes should they use? 

Albinism is an autosomal recessive condition. Which circle graph shows the genotype probability when an albino female mates with a male that is heterozygous for the albinism trait?

In cocker spaniels the allele for a black coat color (B) is dominant over the allele for a brown coat color (b).If a heterozygous cocker spaniel is crossed with a heterozygous black cocker spaniel, which of the following genotypic ratios can be expected?

Chickens can have different types of feathers. Frizzled feathers curl toward a chicken’s head. Assume that feather type is determined by a single gene and that the allele for frizzled feathers is dominant over the allele for straight feathers. In a cross between two chickens with straight feathers, what percentage of the offspring can be expected to have straight feathers?

Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for this trait. If the stem characteristics are determined by a single gene, what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems?

In parrots, green feathers is dominant over blue feathers. If a parrot breeder breeds a homozygous for blue feathers to a homozygous for blue feathers, how many of the 6 eggs laid will have blue feathers?

Independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. Using the image below, what are the possible allele combinations that would be seen in each of the gametes created during Meiosis?
