Monohybrid Crosses (Mendelian Inheritance) question?

In a Punnett square with two guinea pigs of Hh genotype, how many H/h alleles does a baby guinea pig inherit from the:
• mother?
• father?

If a baby girl guinea pig looks almost identical to its mother, does this then mean that it inherited more alleles from its mother? Explain (relate to dominant and recessive).

  1. one allele from mother, one allele from father
  2. yes, this means the mother's alleles are dominant

Explanation:

  1. "The amount of alleles that a baby Guinea pig inherit from the mother are two , 1 from its mother and 1 from its father.
  2. ie: if its mother had a dominant black fur (BB) and its father has recessive grey fur (bb) , there is 100% chance that the baby will has a Bb genotype, which will give them either black fur or dark grey fur."
  3. Yes, the mother likely has several dominant alleles that manifested as a heterozygous genotype in the baby, giving it a phenotype largely similar to its mother.
