Low genetic diversity within a population of Coachella Valley fringe-toed lizards can lead to _____. faster range expansion for the species lower mortality rates higher birth rates higher rates of birth defects and increased susceptibility to disease
Answers
Answer:
increased susceptibility to disease
Explanation:
The correct answer would be increased susceptibility to disease.
Low genetic diversity within a population means that there are few alleles in the gene pool of the population. The implication is that the population will not be able to evolve in response to disruptive influences. There are few alleles available for natural selection to act on. Hence, the population is more susceptible to external influences such as disease outbreak.
Jayden used the multiplication table below to determine that 8:14 is equivalent to 24:42
Answers
Answer: They are both equivalent.
I don't see a multiplication table down below, but I get what you're trying to answer.
Explanation:
8:14 and 24:42 are both the same as 8/14 and 24/42. Multiply both the denominator and numerator by 3 since that's how you solve equivalent ratios. If you try 1 and 2, they will not work. 8*3=24 and 14*3= 42, therefore 8:14.

Hepppp!!! The American curl is a type of cat with curled ears. A single gene with two alleles codes for the ear-shape trait. The dominant allele (R) codes for curled ears, and the recessive allele (r) codes for straight ears. If two curled ear cats produce a kitten that has straight ears, what is the genotype of the parent cats? a Rr x Rr b RR x RR c RR x Rr d Rr x rr
Answers
Answer:
Rr Rr
Explanation: The parents of the cat have to have an R allele to be a curled cat, but they can't be RR because that is a dominant gene, meaning that the recessive trait cannot happen. This means that the parents have to have a recessive trait, which means that they are heterozygous.

A. Sperm cell
B. Feather cell
C. Skin cell
D. Nerve cell
Answers
Answer:
A. Sperm cell
Explanation:
Mutations are genetic alterations in the nucleotide sequence that form the genome of a given organism. In general, mutations have negative effects (i.e., mutations are generally deleterious), but sometimes these genetic changes may be adaptive (and therefore beneficial). Somatic mutations are genetic alterations acquired by somatic cells (they can not be inherited by the offspring), while germline mutations occur in gametes (sperm and egg) and they can be inherited by the offspring, thereby affecting the progeny of the organism.

Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).
