In mice Y is the dominant allele for yellow fur and y is the recessive allele for grey fur. Since Y is lethal when homozygous, the result of cross `Yy xx Yy` will be

In Cucurbita, W is epistatic over Y and y gene normally responsible for yellow and green colour fruits. It produces white flowers. What is the ratio of fruits in the progeny of cross WwYy xx wwYy ?

If'A' respresent the dominant gane and 'a' represent its recessive alleles, what will be result of cross between Aa and aa

An organism has a gene ' X '. Its dominant allele expresses character c - 1 while it's recessive allele expresses character c - 2 This dominant allele is completely dominant over the recessive allele . It has another gene ' y ' which in its dominant form doesn't allow any expression of gene ' x ' which of these genotypes of that organism Will produce character c - 1 ?

In ant lions the gene for dull teeth is dominant D. The recessive gene d produces sharp teeth . Another gene T, when homozygous , produces dark-brown coats . Its allele t, when homozygous , produces albino coats. The heterozygote Tt is chocolate coloured . If a chocolate coloured , dull toothed male whose father was sharp toothed is mated to a chocolate , sharp -toothed female , what is the probability that an albino , sharp - toothed offspring will be produced ?

If 'A' represents the dominant gene and 'a' represents its recessive allele, which of the following would be the most likely result in the first generation offspring when Aa is crossed with aa?
