# What gametes does a RrYy individual make?

Contents

A parent with RrYy genotype can produce four gametes: RY, Ry, rY, and ry.

## What are RrYy gametes?

See if you can verify the following gamete lists for each genotype: RRYY gives RY gametes only RRYy gives RY and Ry gametes RrYY gives RY and rY gametes RrYy gives RY, Ry, rY, and ry gametes. Note that GAMETES NEVER HAVE DUPLICATE LETTERS. So gametes CANNOT look like Aa, or YY, or rr.

## How many gametes will be produced for RrYy?

Answer: A plant with genotype RrYy, produce four types of gametes during fertilization.

## How many different types of gametes can you produce from a heterozygous individual RrYy?

The law of independent assortment states that a gamete into which an r allele is sorted would be equally likely to contain either a Y or a y allele. Thus, there are four equally likely gametes that can be formed when the RrYy heterozygote is self-crossed, as follows: RY, rY, Ry, and ry.

## What are the gametes of a genotype?

The types of gametes produced by each individual depends on its genotype. So, a YY genotype can only produce gametes with Y alleles. An individual with a Yy genotype produces half Y gametes and half y gametes. A yy genotype produces only y gametes.

## What gametes can be produced by TT?

The plant with the RR:TT genotype produces haploid sex gametes that have the genes R:T. The plant with the rr:tt genotype produces haploid sex gametes that have the genes r:t. At fertilization, two of these sex gametes fuse.

## How many gametes will be produced for Aabbccdd?

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

## How many types of gametes can be produced by YYRR?

On selfing F1 we get two possible combinations i.e YR, Yr, yR, yr. Therefore four types of gametes are formed in the ratio of 1:1:1:1. Thus, the correct answer is option D.

## What is genotypic ratio in Dihybrid cross?

This 9:3:3:1 phenotypic ratio is the classic Mendelian ratio for a dihybrid cross in which the alleles of two different genes assort independently into gametes. Figure 1: A classic Mendelian example of independent assortment: the 9:3:3:1 phenotypic ratio associated with a dihybrid cross (BbEe × BbEe).

## How can you tell how many gametes a genotype can produce?

The number of gametes produced by a specific genotype is calculated by the formula 2n, where n= number of heterogeneous alleles present in the genotype. Here, the given genotype consists of two heterogeneous alleles Aa and Bb while CC is homozygous. So, it can produce 22 = 4 types of gametes.
