Having a dimpled cheek is a dominant trait (D) and having a non-dimpled cheek is a recessive trait (d). If someone is homozygous
Ksju [112]
Hope this helps you. 

The genes of an organism can be either a homozygous or a heterozygous one. When someone is a homozygous dominant, it means that it has two copies of the same dominant allele. Homozygous means that the organism has exact copies of the same gene allele.

Similarities between mitosis and meiosis (as many as possible, I really need help)
vesna_86 [32]
Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell. 
so the similarities are: 
-ways for cells to divide 
-same number of chromosome as the original cell 
-both have the basic 5 phases 
-both processes go through chromosome replication 
-Meiosis II is similar to Mitosis 
I hope this is helpful :)))

kherson [118]

Answer:

Ben - Y Xc

Jen - XCXC

Violet - XCXc

Seraphina - XCXc

Samuel- Y Xc

Explanation:

Given -

Ben has a cleft chin

Let the allele for cleft chin be "c"

and the allele for normal chin be "C"

When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.

This means that the allele C could be X -linked and the mother is not the carrier but the father is

The genotype of father Ben would be Y Xc

Genotype of mother would be XCXC

Genotype of two daughters XCXc  , XCXc which means they are carrier for the next generation

Genotype of Boy - Y Xc
