# How many different allele combinations would be found in the gametes whose genotype was RrYY?

Contents

## Which gametes can a RrYy?

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

## How many allele combinations are there?

Each chromosome contains dozens to thousands of different genes. The total possible combination of alleles for those genes in humans is approximately 70,368,744,177,664. This is trillions of times more combinations than the number of people who have ever lived.

## How many alleles are in a gamete for 1 trait?

A gamete has one allele for each gene.

## How many different kinds of gametes may be produced by an organism with the genotype RrYy?

Given genotype is RrYy. As RrYy is a dihybrid. A total of 4 types of gametes RY, Ry, rY, ry are formed.

## What are the allele combinations?

Glossary:Allele Combination. A designation of the specific alleles present on the two homologous chromosomes for all relevant loci of a mouse (i.e., all allele pairs of a genotype). An allele combination can be composed of one or more allele pairs.

## How many combinations of 4 alleles are there?

4 alleles there are 1 + 2 + 3 + 4 = 10 genotypes.

## How do you find allele combinations?

To determine the possible allele combinations of their offspring, alleles from each parent are placed inside their corresponding grid boxes. Because chromosome segregation and fertilization are random, the combinations of alleles in each box are equally likely.

## How do you determine the number of genotypes?

The number of different genotypes is 3 n where n = number of genes. For simple dominant–recessive relations, the number of different phenotypes is 2 n , where n = number of genes.

## How do you know your genotype?

If you prefer finding out your genotype with the help of a blood test, you can visit the hospital nearby, and the doctor will take the blood sample from your arm. When they have enough blood, they take it for analysis to the laboratory. The laboratory test determines the level of hemoglobin in your blood.
