Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offsprin
Andrei [34K]

Answer:

The correct answer would be 2 in 4.

According to the question Xo and XO show codominance and express themselves completely when present in heterozygous condition. Cats bearing XoXO show patchwork of black and orange fur and are called tortoiseshell cats.

Xo codes for orange color fur and XO codes for black color fur. In addition, Y chromosome does not contain any gene associated with fur color.

Now, genotype of mother cat is XOXO (orange fur). So, the gametes formed would be XO only.

The genotype of father cat is XoY(black fur). So, the gametes would be Xo and Y.

The cross would lead to the formation of two male cats each having XOY as their genotype and two female cats each with XOXo as their genotype.

Hence, both the male cats would show orange fur and both the female cats would show patchwork of orange and black fur.

Therefore, we can conclude that 2 out of 4 would exhibit tortoiseshell coloring.

List the sequence of events involved in the alternation of generations in land plants
Keith_Richards [23]
<span>The sequence of alternation of generation is; gametes->zygote->sporophyte->spores->gametophyte->gametes. The attached diagram shows clearly this looped cycle. Alternation of generation occurs in a more advanced land plant that has distinct haploid and diploid phases in their life cycle. The diploid phase usually involves the sporophyte while the haploid phase involves the gametophyte</span>

Ket [755]

Answer:

__Rigor mortis__________ is caused by the lack of adenosine triphosphate (ATP) to the muscles

Explanation:

The rigor mortis corresponds to the stiffness of the muscles (they cannot contract or elongate) due to the lack of ATP, where I fixed the bridges between actin and myosin. This event happens when the oxygen transporting organs stop working.
