What type of inheritance pattern is shown here?

(a)  

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

(a)  

What type of inheritance is determined by multiple genes and there can be a range of traits?

(a)  

A geneticist crossed pure breeding black mice (BB) with pure breeding brown mice (bb). All the mice in the F₁ generation had black coats. When these mice were crossed, they yielded 961 black-coated mice and 317 brown-coated mice. The Punnett square describes this cross. The numbers 1 to 4 are shown instead of the genotypes for the offspring. Which of the genotypes, if any, is MOST likely to occur in the F2 generation?

(a)  

In pea plants, height is determined by an allele for tallness (T) that is dominant over an allele for shortness (t). What is the probability that a gamete, selected at random, would carry the short allele in a cross of heterozygous tall pea plants (Tt x Tt)? (a)  

The inheritance of biological characteristics is determined by individual units called ​ (a)   , which are passed from parents to offspring. Where two or more ​ (b)   of the gene for a single trait exist, some alleles may be ​ (c)   and others may be recessive.

This Punnett square shows flower color inheritance in snapdragons in the F1 generation. This trait shows incomplete dominance. What is the expected ratio of red flowers to pink flowers to white flowers in the F2 generation? (a)  

​ (a)   Coat color in rabbits is expressed in four different phenotypes, and controlled by a single gene.

​ (b)   Leaves on a tree can have different sizes and shapes depending on the amount of light they receive.

​ (a)   The F₁ generation produced by a cross between red-flowered (RR) and white-flowered (rr) plants consists of pink-colored flowers (Rr).

​ (b)   When a certain variety of black chicken is crossed with a white chicken, all of the offspring are checkered. Black and white feathers are produced in the offspring.
