In incomplete dominance, heterozygous<span> phenotype is intermediate between two homozygous phenotypes. In this case, the symbols for alleles are capital letters. For example, allele A is responsible for red color of a flower, allele B is responsible for white color of the flower. Red flower plants have AA genotype, and white flower plants have BB genotype. By crossing plants with red flowers and white flowers, due to incomplete variance, the offspring will be heterozygozs plants (AB) with neither red nor white flowers, but pink flowers. Pink flowers have intermediate color between red and white flowers.</span>
Answer:
Bb ll for the black short-legged horse
bb Ll for the brown long-legged horse
bb ll for the offspring
Explanation:
In order for the offspring to have the two recessive traits, the parents must have been carrying the recessive genes on at least 1 allele. The first horse is black, but it must have a little b for the offspring to gain a little b from it. The second horse and the offspring are brown, so they must both have two little b's. The same goes for the length of the legs. The first horse and offspring must have two little l's because they have short legs and the second horse must have 1 little l in order for the offspring to inherit 1.
The probability is fundamental for calculating the selection coefficient, which can be estimated by a Punnett square.
<h3 /><h3>What is the Punnett square?</h3>
The Punnett square is a diagram employed in genetics to estimate the genotypes and phenotypes derived from a particular genetic cross.
This diagram (Punnett square) can be used to determine the selection coefficient for different genes and thus estimate the time required (n generations) for selective breeding programs.
Statistics and probabilities play a central role in genetics, especially to estimate additive effects in complex quantitative traits influenced by many genes.
In conclusion, the probability can be estimated by a Punnett square.
