Dominant phenotype in all offspring resulting from test cross indicates the the parent with dominant phenotype is homozygous. Thus, the test-crossed chestnut trotter had genotype TT, the organism, with which it was crossed had genotype tt, and their offspring were all Tt.

What will be the probable number of type of genotypes in a cross AABBCC×aabbcc in F2 ? a)27 b)64 c)8 d)81

Your F1 generation will be doubly heterozygous: AaBbCc, so crossing two of these individuals will give us how many genotypic combinations? How many genotypes can be produced in the offspring...

Rough-coated guinea pigs crossed with smooth-coated ones produce only rough-coated offspring. What results would be expected from breeding here offspring with each other?

As all the offspring are rough-coated offspring, it is a dominant trait. These offspring are heterozygous. If two heterozygous organisms from the first generation are crossed, the 3:1 ratio will...

When Mendel crossed a true-breeding purple-flowered pea plant with a true-breeding white-flowered pea plant, the probability of the genotype (Pp) to appear in the offspring is, what is the ratio

Genotype of one true-breeding parent is PP. The other true-breeding parent has genotype pp. So, all offspring will be heterozygous. The probability for Pp is 100%, there will be no...

In pea plants, purple flowers are dominant to white flowers. If two white flowers are crossed what percentage of their offspring will aslo be white?

100%Since White is recessive, if you cross aa and aa, the only possible offspring will have aa only

In squash plants, yellow fruit (Y) is dominant to white fruit (y). If two plants heterozygous for yellow fruit are crossed, what are the possible genotypes of the offspring?

For this to be possible, one parent would have to be homozygous dominant and the other would have to be homozygous recessive.

When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.

Incomplete dominance because there is blending of colours.
