Question

Evaluate the possible genotypes the offspring could inherit for traits 1, 2, and 3. Use percentages to explain the probability that an offspring will inherit each possible genotype.

a) Homozygous dominant (25%)
b) Heterozygous (50%)
c) Homozygous recessive (25%)

Answer 1

In a tetrahybrid cross, the possible genotypes and their probabilities can be calculated using the sum and product rules of probability. The genotypes can be homozygous dominant (25%), heterozygous (50%), or homozygous recessive (25%).

Step-by-step explanation:

In a tetrahybrid cross, where there are four traits being considered, the possible genotypes and their probabilities can be calculated using the sum and product rules of probability.

For each trait, the possible genotypes and their probabilities are:

1. Homozygous dominant (25%): This means both alleles for the trait are dominant. Example: BB.
2. Heterozygous (50%): This means one allele is dominant and one allele is recessive for the trait. Example: Bb.
3. Homozygous recessive (25%): This means both alleles for the trait are recessive. Example: bb.

By considering the percentages, we can calculate the probability that an offspring will inherit each possible genotype.

The primary topic of this question is genotypic probabilities in genetics.
