Biology

quester [9]3 years ago

Answer:

Mutations are naturally caused by errors in DNA replication, by physical or chemical methods. The mutations change the genetic makeup of the organism and introduce new alleles or combination of alleles in a population. These random mutations accumulate over time and increase the genetic variation among the population.

a black rooster Mated with a white hen. based on genotypes, the chance that the offspring will be checkered is 100 percent. what
gtnhenbr [62]

Answer:

The genotypes of the rooster and the chicken are homozygous and that of their offspring is heterozygous.

This case is called codominance, where the offspring receives an allele from each parent, from the rooster and the hen, because there is codominance, so neither allele is recessive and the phenotype of both alleles is expressed so the phenotype of the offspring is checkered.

We can say then that the chicken and the rooster have equal strength between their alleles. in the cases of codominance the laws of mendel do not apply.
