Options for the question are not given. They are as follows :
A. Mate them and see what color the offspring are—that will be the dominant color
B. Mate them and see what color the offspring are—the other will be the dominant color
C. Mate them, and then mate their offspring to see what color the next generation is
D. Mate them together, and then mate their offspring to see what color the next generation is—the other color will be the dominant color
Answer:
A. Mate them and see what color the offspring are—that will be the dominant color
Explanation:
Out of the two colors, one will be recessive and one will be dominant. Recessive color will be homozygous since it is only expressed in homozygous condition. It is also given that in this cross the dominant color is also in homozygous condition.
When the guinea pigs mate, the resulting progeny will obtain one dominant allele from the dominant color parent and one recessive allele from the recessive color parent. The progeny will be heterozygous and show the dominant phenotype since the dominant allele will mask the recessive allele. Thus, the color which is visible in their offspring will be the dominant color.
A mistake in DNA replication before meiosis produces an organism that is better able to outrun predators.
Explanation:
The genetic variation results from the different alleles of a population. The mutation or mistake in DNA replication would cause gene variants which may be beneficial. The variation in the DNA sequence of genome results in variants in small population.
Genetic variation is the cause of natural selection and eventually, evolution takes place with beneficial traits.
It is mentioned in the question that resulting offspring having received the mutant allele could result in better surviving capabilities or phenotypic traits as they are able to outrun predators.
Answer:
Explanation:
The purpose of the dihybrid cross was to determine if any relationship existed between different allelic pairs
To determine if one trait could affect the inheritance of another trait
Answer:
D.
Explanation:
Sana tama kase feel ko pang
The answer is A because in the process of mitosis and meiosis chromosomes are single-stranded groups that are condensed to chromatin when the process of division of cells chromosomes replicate to make sure that the new daughter cells received the correct number of chromosomes
