What do letter F 1 And F 2 Represent in heredity studies?

F 1 Term means the first filial generation, and it shows hybrids generated from a cross among the genetically distinct people called parents. F 2 Represents the second filial generation, and it arises as a result of inbreeding of interbreeding between the individuals of F 1 Generation. F 1 generation and F 2 generation are the used in the genetics which is a branch of biology.

Given below is a table showing the genotypes of blood groups in the human population. S.no Genotype Phenotype 1. I A I O A-Phenotype for Y 2. I B I O B-Phenotype for Z 3. I A I B AB 4. X O Name the pattern of inheritance exhibited by the phenotypes Y and Z in the table.

See the answer table given below S.no Genotype Phenotype 1. I A I O A (Y) 2. I B I O B (Z) 3. I A I B AB 4. ii O Y: The allele I A is dominant over i and hence, the phenotype is A group. So it follows law of dominance. Z: The alleles I B is dominant over I O hence the phenotype is B. It also follows the same patterns of inheritance.

What is the cross between the F 1 progeny and the homozygous recessive parent called?

F 1 is also known as the first filial progeny. It always resembles either of the parents and that the trait of other parent was not seen in them. The cross between the F 1 progeny and the homozygous recessive parent is called the Test cross.
