Answer 1

2(PMAT + C)

Question 2

What is the difference between meiosis 1 and 2

Answer 2

Meiosis 1 deals with homogulous pairs, while 2 deals with sister chromatids

Question 3

What does meiosis produce?

Answer 3

4 unique haploid cells

Question 4

What is complete dominance, and its ratio?

Answer 4

Dominant allele completely takes over recessive (3:1)

Question 5

What is co-dominance, and its ratio?

Answer 5

Heterozygous will have both phenotypes (blue with yellow spots) (1:2:1)
