In a matting between two individuals wha are heterozygous for a trait, what is the probability the offspring will express the trait recessive? What percent?

1/4 or 25% chance of expressing recessive genes

Explanation:

Punnett Square ( Dominant B, recessive b)

~ B | b

B | BB | Bb

b | Bb | bb

1/4 or 25% chance of hom0zygous dominant (hom0zygous dominant)

1/2 or 75% chance of expressing dominant gene (heterozygous with recessive gene hidden)

1/4 or 25% chance of expressive recessive gene (hom0zygous recessive)

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
