weeeeeb [17]

Answer:

41 chromosomes

Explanation:

Cats have a dipoid chromosome number of 38, <u>so their gametes will have half that number: an haploid number of 19 chromosomes</u>.

Rabbits have a dipoid chromosome number of 44, <u>so their gametes will have an haploid number of 22 chromosomes</u>.

When a cat gamete (n=19) joins with a rabbit gamete (n=22) to form the hybrid zygote, it will have 19+22=41 chromosomes. When it undergoes mitotic division, all its somatic cells will have 41 chromosomes.

KEY TAKEAWAYSKey PointsOrganisms may be very closely related, even though they look quite different, due to a minor genetic change that caused a major morphological difference.Unrelated organisms may appear very similar because both organisms developed common adaptations that evolved within similar environmental conditions.To determine the phylogeny of an organism, scientists must determine whether a similarity is homologous or analogous.The advancement of DNA technology, the area of molecular systematics, describes the use of information on the molecular level, including DNA analysis.Key Termsanalogous: when similar similar physical features occur in organisms because of environmental constraints and not due to a close evolutionary relationshiphomologous: when similar physical features and genomes stem from developmental similarities that are based on evolutionphylogeny: the evolutionary history of an organismmolecular systematics: molecular phylogenetics is the analysis of hereditary molecular differences, mainly in DNA sequences, to gain information on an organism’s evolutionary relationships
