Complete a Punnett Square and answer the questions. Show all work.

Chin cleft in humans

Chin cleft is dominant (C)

No chin cleft is recessive (c)

Both parents are heterozygous

What are the genotypes/phenotypes of the parents? & What are the genotypes/phenotypes of the offspring?

(If the answers could be written or typed out instead of cursive lettering, due to visual impairment)

Thank you.

Answer #1

Given : Chin cleft dominant (C)

Chin cleft recessive (c)

Both parents are heterozygous.

The cross we are going to do here is hetrozygous cross between two parents

According to Mendilian cross there are 4 offsprings will be produces where one is pure / homozygous child having chin cleft. 2 will be heterozygous dominant chin cleft and only one offspring will be without chin cleft. It is recessive one.

The percentage of dominant and recessive offsprings would be 75% and 25%.

Punnett square :

The punnett square shows there are 4 offsprings out of which 3 are with chin cleft and one offspring is no having no chin cleft.

The phenotypic ratio of the offsprings are 3 : 1

It means 75% child are with chin cleft, and 25% offsprings have no chin cleft.

If we see according to Mendel's cross the 1 is homozygous dominant chin cleft child i.e. CC

the 2 are heterozygous dominant child with chin cleft Cc

one is recessive and have no chin cleft i.e cc

Both the parents are heterozygous and having chin cleft i.e. Cc.

Probability and Genetics Lab In heredity, we are concerned with the occurrence, every time an egg is fertilized, of the probability that a particular gene or chromosome will be passed on through the egg, or through the sperm, to the offspring. As you know, genes and chromosomes are present in pairs in each individual, and segregate as they go into the gametes (egg and sperm). There are two possible genes (alleles) that the egg or sperm might obtain from each...
