How many genetically different gametes can be produced by AaBb?

There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.

How many genetically different gametes can be produced?

But what about chromosome reassortment in humans? Humans have 23 pairs of chromosomes. That means that one person could produce 223 different gametes. In addition, when you calculate the possible combinations that emerge from the pairing of an egg and a sperm, the result is (223)2 possible combinations.

How many types of gametes would be produced if the genotype of a parent is AaBb a 1b 2c 3d 4?

Complete answer: AABbcc will produce 2 types of gametes which are as follows- ABc, Abc.

What genotype is AaBb?

A heterozygous for two genes AaBb has two types of alleles for each gene: A and a, B and b. The assortment of “A” and “a” into gametes is independent of the assortment of “B” and “b”.

How many genetically different types of sperm could an animal that has the genotype AaBb produce?

A diploid cell would be AaBbCcDdEe. Since small case letters represent paternal chromosomes, a paternal haploid set would be represented as abcde. 14. The number of different possible gametes produced by the diploid genotype (AaBbCcDdEe) is 2 x 2 x 2 x 2 x 2 = 32 (2 for each pair of heterozygous genes).

What kind of gametes can be produced by a AA genotype?

An individual with the genotype Aa can make two types of gametes: A and a. Since this is a random process, the individual will, on average, make equal numbers of each gamete.

How many gametes can be formed from Aabbccdd?

One type by AABBCCDD & 16 type by individual Aa Bb Cc Dd 24 = 16.

How many types of gametes would be produced if the genotype of a parent is AaBb a 1 b 2?

If the genotype of a parent is AaBB then 2 types of gametes will be produced.

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 gametes does Trihybrid produce?

The F1 hybrid produces 8 types of gametes.

How many genetically different gametes can be produced by an Rryygg genotype?

How many different gametes can an RrYy parent form? A parent with RrYy genotype can produce four gametes: RY, Ry, rY, and ry.

When AaBb and AaBb are crossed in f2 generation the ratio of AaBb will be?

1 : 2 : 2 : 1.

Is AaBb homozygous dominant?

We now consider a dihybrid cross. This time there are two sets of alleles for parents to pass on to their offspring. … Both parents are heterozygous and so they have the genotype of AaBb. Since they both have dominant genes, they will have phenotypes consisting of the dominant traits.

How many different possible gametes can be obtained from an organism with the following genotype AaBbCc?

These types of genotypes that are ABC, ABc, AbC, and Abc will be found in the gametes. Thus the number of gametes produced by the plant having the genotype AABbCc is four.

How many unique gametes could be produced through independent assortment by an individual with the genotype AaBbCcDd?

How many unique gametes could be produced through independent assortment by an individual with genotype – AaBbCCDdEE? – Quora. The answer is eight. Eliminate the Cs and the Es — since the individual is homozygous at those loci, they can only produce one kind of gamete (with a C and an E).

How many different gametes are there?
