I mice, albino is recessive to nonalbine. Suppose that a true-breeding nonalbino srain is crossed with a true-breeding albino strain. The F1 generation are mated with each other to produce an F2 generation of 100 mice. How many albinos and nonalbinos are expected in the F2 generation if this trait follows Mendel's law?

An experiment to determine the inheritance of fur color mates two mice. A true breeding mouse with purple hair is crossed with a true breeding mouse with red hair. All the offspring (F1 generation) are purple.

A) Based on this, what is the dominant trait and the recessive trait?

B) What is the genotype of all of the F1 generation?

The F1 animals are crossed and produce the following (F2) progeny.

290 purple mice

110 red mice

C. Do these numbers make sense?.. What is your hypothesis that would explain the ratio of the F2 progeny?

D. Use a Chi-square test to determine whether those numbers fit a Mendelian pattern of inheritance

In mice, females are XX (ie., 2 X chromosomes) and males are XY.Locus 1: allele E =ears; e = no ears. Locus2: allele B = black hair; b = white. Upper case letter isdominant. Previous research determined that the locus 2 was part ofan X chromosome and locus 1 was part of an autosome. Parents & phenotypes: thisis a reciprocal cross relative to the genotypes and phenotypesdescribed in question 1. Both parents are true-breeding. Theparents mate to produce the F1 generation. The F1-generation micemate to produce the F2 of400 mice.

A geneticist has obtained two true-breeding strains of mice,each homozygous for an independently discovered recessive mutationthat prevents the formation of hair on the body. One mutant strainis called naked, and the other is calledhairless. To determine whether the two mutations arealleles, the geneticist crossed naked andhairless mice with each other. All the offspring arephenotypically wild-type; (i.e., they have hairs all overtheir bodies). After crossing the wild-type F1, the geneticistobserves 115 wild-type mice and 85 mutant mice in the F2.
1. (a) Determine the relationship between naked andhairless.
2. (b) Explain the reasoning behind your answer to part (a).
3. (c) What is the expected phenotypic Mendelian ratio withcorresponding phenotypes for F2
