What are the possible gametes for WW?

Is WW dominant or recessive?

The genotypes WW and Ww will produce a widow’s peak (the dominant phenotype) and the ww genotype will produce no widow’s peak (the recessive phenotype). If we know the genotype of the parents, we can predict the possible genotypes and phenotypes in their offspring (first generation).

What gametes can be produced by AA?

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.

Are alleles inherited?

The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways. These are called inheritance patterns.

What nationality has a widow’s peak?

Why is it called a widow’s peak? The term “widow’s peak” may be a holdover from 18th-century England. Tradition was that when a husband died, his wife would wear a black triangular hat or hood with the point falling in the middle of the forehead.

What are gametes?

Gametes are an organism’s reproductive cells. 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 cells develop into sperm or ova.

What are gametes example?

In short a gamete is an egg cell (female gamete) or a sperm (male gamete). … This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell).

How many types of gametes are there?

In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile.

How many gametes can an individual make?

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 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 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 are the four possible gametes after independent assortment?

Thus, there are four equally likely gametes that can be formed when the YyRr heterozygote is self-crossed as follows: YR, Yr, yR, and yr.
