Identify the types of genetic recombination.
A occurs in metaphase I.
occurs during sexual reproduction.
A is random chromosome alignment resulting in variation.
A occurs in prophase I.
fuses gametes to form offspring with genes from each parent.
exchanges genetic information between non-sister chromatids.

In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants were “true breeding” for pea shape; one had round peas ( r )and the other had wrinkled (r). the first cross produced a filial 1 generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.

Freckles are a dominant trait in humans. both of the girls have the genotype ff for freckles. if either one marries a man with no freckles, what are the chances that their children will have freckles?
