What are the possible gametes for each parent?

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.

What are the possible gametes?

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 children could be produced from the combinations of your parents gametes?

Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. Sexual reproduction results in offspring that are genetically unique. Each human couple has the potential to produce more than 64 trillion genetically unique children.

IT IS SURPRISING:  Which statement describes how two organisms may show the same trait yet have different genotype for the phenotype?

What are the percentages of each offspring?

These percentages are determined based on the fact that each of the 4 offspring boxes in a Punnett square is 25% (1 out of 4). As to phenotypes, 75% will be Y and only 25% will be G. These will be the odds every time a new offspring is conceived by parents with YG genotypes.

What are the possible gamete types that can be produced from a parent who is YyRr?

What are the possible gamete types that can be produced from a parent who is YyRr? Meiosis produces eggs and sperm that are alike.

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.

What are the possible phenotypes of the offspring?

Eye color, hair color, pod shape, and flower position are all examples of phenotypes. In this example, it asked you to do a cross between two parents who were homozygous dominant for eye color. Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene.

How many gametes do humans have?

We have 23 pairs each with 50/50 probabilities. That works out to 223 possible combinations of gametes from one human individual. That’s over 8,000,000 (8 million). That’s a lot.

How many genetically unique gametes can a human produce?

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.

IT IS SURPRISING:  Does segregation of alleles occur in meiosis 1 or 2?

Why different gametes produced by the same person can have different combinations of alleles for genes that are located on two different chromosomes?

When gametes are produced (by meiosis), the paired homologous chromosomes separate so that each gamete contains only one of the pair of alleles for each trait. … As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.

How many types of gametes are formed by a parent having genotype AABbcc?

Complete answer: AABbcc will produce 2 types of gametes which are as follows- ABc, Abc. The number of gametes formed is set by the number of heterozygous alleles present within the given genotype.
