Answer:

The correct answer would be meiosis.

During meiosis, recombination takes place in the form of crossing over.

It is an event that takes place during the pachytene stage of prophase I of meiosis I.

During this event, the genetic material gets exchanged between non-sister chromatids of homologous chromosomes.

It results in the production of new combinations of genes which are not present in either parent and thus, results in the genetic variation in a population.

Answer:

The correct answer is option B) "Mendelian".

Explanation:

Transmission genetics is basically the study of how traits and characteristics are passed from one generation to the next. This branch of modern genetics study is also known as “Mendelian Genetics” in honor to Gregor Johann Mendel, the scientist how described the rules of heredity with the study of the characteristics of pea plants and how they transfer them among the generations.

Black fur (B) is dominant to white fur (b) in guinea pigs. An F1 cross was conducted and resulted in 100% heterozygous guinea pi

Lemur [1.5K]

Answer:

D. 1 BB : 2 Bb : 1 bb

Explanation:

This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.

If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:

Bb = B and b

Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:

1 BB : 2 Bb : 1 bb

BB and Bb = black fur guinea pigs

bb = white fur guinea pigs
