Quick Answer: What kind of gametes can a heterozygous produce?

How many gametes can a heterozygous produce?

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).

Can gametes be heterozygous?

MESSAGE. Meiosis in a heterozygous meiocyte results in haploid products (for example, gametes) half of which carry one allele, and half the other allele; for example, A / a → 1/2 A and 1/2 a . … The four sexual spores that represent the products of a single meiosis are held together as a tetrad.

How many gametes can a homozygous produce?

Here, the given genotype consists of two heterogeneous alleles Bb, and Cc while one homozygous allele is AA. So, it results in the production of 22= 4 types of gametes.

What types of gametes can be produced?

They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.

What gametes would be produced by an organism with the genotype hh?

What gametes would be produced by an organism with the genotype Hh? The gametes will either have H or h.

What kind of gametes can an individual with the genotype BB produce?

Therefore, each allele for a given gene is packaged into a separate gamete. For example, a fly with the genotype Bb will produce two types of gametes: B and b. In comparison, a fly with the genotype BB will only produce B gametes, and a fly with the genotype bb will only produce b gametes.

What is heterozygous seed color?

Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color. yy is the homozygous dominant genotype (2 y alleles).

Is BB homozygous or heterozygous?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.

How many different types of gametes are produced by an individual with the genotype AaBbCcDd?

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

How many types of gametes can be produced by a diploid organism who is heterozygous for 4 loci A 4 B 8 C 16 D 32?

If a diploid organism is heterozygous for 4 loci then it will have four contrasting traits Aa, Bb, Cc, Dd and during meiosis 16 different kinds of gametes will be formed.

How many types of gametes can be produced by a diploid organism who is heterozygous for 3 loci?

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

How many different kinds of gametes will be formed by an individual who is heterozygous for four gene pairs?
