c. testcross

d. monohybrid cross

Expert Solution

The correct option is d.monohybrid cross.

Mendel's first law is also known as the law of segregation. The law of segregation is the condition that, 'the alleles of a given locus segregate into separate gametes.' Alleles sort independently because the gene is located on a specific chromosome.

Mendel formulated the law of segregation as a result of performing monohybrid crossexperiments on plants.A monohybrid cross involves one character and different (hybrid) traits.The specific traits which were being studied exhibited complete dominance.In complete dominance, one phenotype is dominant and the other one is recessive.

You perform a dihybrid cross of plants. The first trait is flower color. “A” is the dominant allele and causes red petals and “a” is the recessive allele and causes white petals. Stem length is the second trait. “L” is the dominant allele and causes a long stem and “l” is the recessive allele and causes short stems. You cross a Red Long plant that is heterozygous for both traits with a Red Short plant that is heterozygous for color....

A dihybrid cross is performed in Drosophila - one parent is heterozygous for both genes (B/b ; F/f) and is test-crossed with a homozygous recessive type (b/b ; f/f). (where B = black body; b = brown body; F = forked bristles; f = unforked bristles.) The results are: black, forked 230 black, unforked 210 brown, forked 240 brown, unforked 250 How many degrees of freedom would you use in this case? What would be the expected number for each...
