Homozygous dominant and heterozygotes produce 4 offspring per individual on average, while the homozygousrecessives produce 8 on average. But all offspring survive at the same rate.

6. Mating of two organisms produces a 1:1 ratio of genotypes in the progeny. The parental genotypes are: AAA*AA, AA*Aa, AA*aa, and Aa*Aa. Consider a gene with three alleles: A, A', and A". In a cross between two individuals with genotypes A,A' and A'A", what is the probability that a particular offspring will have the A' allele? 8. A monohybrid cross is carried out: the recessive homozygote always dies at birth. What fraction of the progeny will be dominant homozygote in F1?
Adi S.
When mating two heterozygotes for alleles in which one is dominant to the other, if the usual Mendelian segregation process is occurring, the ratio of the offspring phenotypes produced should be 3:1. The dominant phenotype would be more common than the recessive one. Imagine a situation in which two heterozygotes are mated and among their 200 offspring, 160 show the dominant phenotype while 40 show the recessive phenotype. What is the P-value of a two-sided binomial test using the normal distribution to approximate the binomial? 0.031 0.015 0.121 0.060

If two heterozygous genotypes crossed, the resulting offspring genotype ratio is [ Select ] homozygous dominant : [ Select ] heterozygous : [ Select ] homozygous recessive.
