The first filial generation is the result of?

The first filial generation is the result from a cross between parents homozygous for different alleles at a locus. This is when where an individual inherits the same alleles for a particular gene from both parents.


What is the generation of the offspring of a cross between parents that are pure for a given trait?

The first generation cross, known as F1 (filial 1), for homozygous (purebred) parents will be heterozygous - have one allele of each of their parents' traits. For example, the cross BB X bb would result in an F1 genotype of Bb.


Offspring that result from crosses between parents with different traits?

genes


What happens to the alleles between the P generation and the F2 generation?

In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.


What did mendel call the offspring of the first filial generation?

Mendel called the offspring of the first filial generation "F1 hybrids" or "first filial generation." These offspring result from crossing two true-breeding parents with different traits.


Variation in a new generation is he result of?

Variation in a new generation is the result of a combination of genetic factors inherited from the parents, as well as random mutations that occur during the process of DNA replication. These variations contribute to the diversity seen within a population and are essential for natural selection and evolution.


How do inherited genes make a tiger cub closely resemble its parents?

Every living thing on this planet has genes. What genes mainly do is tell your body how to build itself. They are like a construction plan. The genes go on from generation to generation. The father's genes go together with the mother's genes and the result is something that is like the parents. Basically, the cub closely resembles its parents just like you resemble your parents.


What is generation of all hybrids produced by crossing two pure organisms?

The generation produced by crossing two pure organisms is called the F1 generation. This generation is the first filial generation and consists of hybrids that are a result of the cross between the two pure organisms.


The first generation of offspring from the cross of two parents is called?

Durrrrr whats the trait??? Assuming this is what your really asking. Its PP X PP Then the result can only be PP if big P is dominant over little p. Form your questions better in the future! Apex: 100 percent heterozygous


What was the result of the first generation of pea plants that mendel bred?

P generation.


What is an F1 offspring?

An F1 offspring refers to the first generation of offspring resulting from the crossbreeding of two parental organisms or strains. This generation is often used in genetic studies to observe the characteristics that result from the combination of genetic material from the two parents.


Which punnett square shows the result of a cross between two heterozygous parents?

A cross between two heterozygous parents (eg. Gg X Gg) would result in a phenotypic ratio of 3 dominant : 1 recessive, and a genotypic ratio of 1GG:2Gg:1gg.GgGGGGggGggg
