Practice: Calculate the probability of 2 heterozygous (Rr) parents having 3 homozygous recessive (rr) offspring.

Practice: What is the probability that a plant from a monohybrid cross of heterozygous parents, is homozygous dominant OR homozygous recessive?

Practice: A blue-eyed female that is homozygous recessive and a brown-eyed male that is heterozygous mate, producing two offspring. What is the probability that one child will have blue eyes AND one will have brown eyes? (Eye color is controlled by a single gene).

Practice: A homozygous dominant male has a child with a heterozygous female. What is the probability that the child will have the same genotype as its father OR its mother?

An individual with genotype AaBbccDd is crossed to an individual with genotype aaBbCcDd. What is the probability that their first offspring will have genotype aabbCcDD?a) 1/64 b) 1/32 c) 1/16 d) 1/8e) 1/4

In cattle, the gene for hornless (H) is dominant to the gene for horned (h), the gene for black (B) is dominant to that of red (b), and the gene for white face (or Hereford spotting) (S) is dominant to that for solid color (s). A cow with the genotype BbHhSs is inseminated by a bull of the genotype bbhhSs. What is the probability of the calf's being:i) a black, hornless cow with Hereford spottingii a red, horned bull with solid coloriii) a red, hornless bull with Hereford spotting

A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have a normal number of digits. Having extra digits is a dominant trait. The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16b. 3/4c. 1/16d. 1/2e. 1/8

Given the cross PpQqRrSS x PPQqRRSs, what proportion of offspring are expected to be PPQQRRSS?a. 1/32b. zeroc. 3/64d. 1/16

When crossing one parent having an RRBbDd genotype with another parent having an RrBbDd genotype, what is the probability that they will have an RrBBDd offspring?a. 1/8b. 1/16c. 1/32d. 3/16e. 1/64

In a species of butterfly, the blue-wing allele (B) is dominant to the yellow wing allele (b) and the allele for long antennae (L) is dominant to the allele for short antennae (l). If a butterfly is homozygous recessive for antennal length, its wings always end up being blue. If one butterfly is Bbll and a second butterfly is BbLl, what is the chance that they will produce offspring that have short antennae and blue wings?a. zerob. 3/8c. 1/2d. 3/4e. 1/1

In a cross AaBbCc x AaBbCc, what is the probability of producing the genotype AABBCC?a. 1/4b. 1/8c. 1/16d. 1/32e. 1/64
