What causes recombinant phenotypes?

What causes recombinant phenotypes?

Different allele combinations create different phenotypes. Recombinant offspring are children that have a different allele combination to their parents. The AB and ab haploid cells are the same as the parental type, while the Ab and aB are the recombinants due to the fact that they differ from the parental types.

What is a recombinant phenotype?

Recombinant phenotypes are the phenotypes of the offspring that differ from that of the true-breeding P generation parents. Mendel observes that some combinations of traits in the offspring differ from either parent. These phenotypes are identified as nonparental or recombinant phenotypes.

What are recombinants in meiosis?

Recombination in meiosis. Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.

Does recombination occur in mitosis or meiosis?

Recombination Occurs During Meiosis of Higher Organisms In mitosis, recombination serves to repair double-stranded breaks or single-stranded gaps in the chromosomes.

How do you determine recombinants?

It is usually a simple matter to determine which of the gametes are recombinant. These are the gametes that are found in the lowest frequency. This is the direct result of the reduced recombination that occurs between two genes that are located close to each other on the same chromosome.

What stage does recombination occur in meiosis?

Prophase
Recombination Occurs During the Prolonged Prophase of Meiosis I. Prophase I is the longest and arguably most important segment of meiosis, because recombination occurs during this interval. For many years, cytologists have divided prophase I into multiple segments, based upon the appearance of the meiotic chromosomes.
