7 0

Answer:

The correct option is Number 1. AaBb x AaBb

Explanation:

Genes can be described as basic hereditary units. The genes are made up of DNA.

A gene carries two alleles for a particular trait. These alleles are present at the same loci in the homologous chromosomes. If the two alleles are similar then they are termed as homozygous e.g AA, BB. If the alleles for a trait are different then they are termed as heterozygous e.g Aa and Bb.

Eddi Din [679]

Answer and Explanation:

Corals are a type of invertebrate within the <u>phylum Cnidaria</u>. They live in colonies of many identical individual polyps.A set of tentacles surround a central mouth opening. They also have a simple, radially-symmetrical body containing a single opening that serves as both the mouth and anus. The body is made up of two layers of cells, separated by a jelly-like layer with no internal organ. The two layers of cells make a single cell surrounding the body.

zvonat [6]

Answer:

25%

Explanation:

Let's assume that the recessive allele "p" imparts diseased conditions in the homozygous genotypes. The genotype of each of the carrier parents would be "Pp". A cross between Pp and Pp would produce progeny in the following phenotype ratio=

Pp x Pp= 3/4 Normal : 1/4 Affected.

Therefore, there are 1/4 or 25% chances for this couple to have a child with PKU.
