In a cross, Aa Bb Cc Dd Ee x Aa Bb cc Dd ee, what proportion of offspring are expected to be homozygous recessive for all five genes? show your work.

The cross AaBb x aaBB results in which of the following phenotypic ratios? 1:1 1:1:1:1 1:2:1 9:3:3:1

Mendel counted thousands of pea plants for each cross in his experiments before reaching his conclusions. Why did he need to count so many? Each kernel you counted in this lab is an offspring resulting from sexual reproduction. Name three processes that contribute to variation in sexual reproduction.

You are conducting independent research for your Honors Thesis in a Drosophila research lab.  One of the graduate student researchers has provided you with two mutant strains of Drosophila.  One has scarlet eyes, and the other has brown eyes.  You cross homozygous scarlet-eyed male Drosophila with female flies homozygous for the brown-eye color allele, and all of the male and female F1 flies have wild-type eyes.  Crosses involving F1 males x F1 females yield the results shown below. You know the traits involved are autosomal, and that reciprocal parental crosses produce similar results.   a) What is the phenotypic ration observed among the offspring in the F2 generation? b) How many pairs of genes are involved in determining these traits? Please explain in detail. c) Please EXPLAIN the genetic basis for the pattern of inheritance illustrated in this cross. Be sure to mention the alleles involved.

Can you show the cross to know how to get the answers?. And some explanation would be helpful. Please Recombinant

A dog breeder liked yellow and brown Labrador retrievers. In an attempt to produce yellow and brown puppies, he mated a yellow Labrador male and a brown Labrador female. Unfortunately, all the puppies produced in this cross were black.  Q. Explain this result.

The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…
