Problem # 2: One parent will have one type of gamete and the other two types of gametes, since their genotypes are RR & RW.
How many types of offspring will each parent produce in Problem 1 and 2?
Answer: 1. Each parent has four different combinations of alleles in the gametes, there are sixteen possible combinations for this cross. 2.
What percentage of gametes will each parent frame?
Predicting the genotype of offspring
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 do you calculate the number of different types of gametes?
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.
What are gametes What are the types of gametes Brainly?
Gametes is an organism’s reproductive cells. They are also called as sex cells. Female gametes is referred as ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and every cell carries only single copy of each chromosome.
What is phenotype example?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What is the genotypic ratio?
▪ Genotypic ratios: The ratio of different genotype in the offspring from a genetic cross. E.g 1:2:1. ▪ Phenotypic ratios: The ratio of different phenotypes in the offspring from a genetic cross.
How many gametes does each parent produce?
There are two types of gametes will each parent produce and that is either recessive or dominant.
How do you calculate gametes?
Simply place a 2 above each heterozygous gene pair and a one above each homozygous gene pair. Then multiply the numbers together to obtain the total number of different possible gametes.
How many different kinds of gametes could the following individuals 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).
Are gametes haploid or diploid?
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.
How do you determine the number of genotypes?
c. 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.
