## How many different gamete genotypes can each organism produce?

Each organism can produce four different genotypes.

## How many possible gametes can be formed by each?

Hints For Biology 101 Exam #4

No. of homologous chromosome pairs (heterozygous genes) No. of different gametes from each parent
2 (AaBb X AaBb) 4 (22)
3 (AaBbCc X AaBbCc) 8 (23)
4 (AaBbCcDd X AaBbCcDd) 16 (24)
20 pairs of chromosomes 1,048,576 (220)

## How many different gametes can be made by an individual with the genotype AaBb quizlet?

An individual with the genotype AaBb produces four different gametes in equal proportions.

## How many types of gametes can be produced by a diploid organism?

Types of gametes =2n where n is number of heterozygous loci. Thus, gametes produced by a diploid organism could be 24=16.

## How many types of gametes are produced by a Trihybrid?

The F1 hybrid produces 8 types of gametes.

## How many kinds of genotypes will be produced in the cross?

These four genotypes can produce one, two, two, and four different gametes, respectively (Table 3). Moreover, in combination with the single gamete from the “tester” parent, these gametes will produce one, two, two, or four progeny phenotypes.
